I think that's the Norfolk Broads (either way you could tackle it on a large boat).
Back on Topic though, it seems obvious to me that it's not a picture of Bella. 30s floating around under that would be guaranteed to submerge you for good.
I might get to see her, I'm nearby this week. If she looks like a Hoseasons (pun intended) vessel, I shall walk. If not, I'll go through with it and report back.
